An open source, Arduino-compatible RF signal generator with Wi-Fi connectivity

One of the most frequently asked questions about ERASynth was about availability of analog modulation functionality. When we designed ERASynth’s current revision, we payed attention to do it such that basic analog modulation types could be implemented by software. We were planning to leave to users, but since we received so many questions, we decided to work on it. We have implemented basic AM and pulse, and are still working on FM. We haven’t fully characterized the performance yet. For now we can say: AM rates up to 10 kHz for external input and AM rates up to 3 kHz when using internal generator can be generated with ERASynth.
